1+(x-1)/2 =3x

1 + \frac{x - 1}{2} = 3 x

x = \frac{1}{5}

Decimal Notation

x = 0.2

Solution steps

1 + \frac{x - 1}{2} = 3 x

Move

1

to the right side

\frac{x - 1}{2} = 3 x - 1

Multiply both sides by

2

x - 1 = 6 x - 2

Move

1

to the right side

x = 6 x - 1

Move

6 x

to the left side

- 5 x = - 1

Divide both sides by

- 5

x = \frac{1}{5}

(4 x^{3} yz)^{3}

(x + 4) (x + 3) = 2

- (5)^{- 1}

30 x = 2 (3 x + 8) + 4 (x - 4)

5 x^{2} - 9 x + 4
